The nonradiative changeover premiums Stick to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative peace charges is complicated through the
